It looks like this:
Note also that using the attribute value default technique to
specify the XLink namespace declaration has no equivalent in [RELAX
NG], [XML Schema Part 1: Structures], or other modern schema
languages. While it can be used when DTD-informed parsing is
performed, it poses an interoperability risk and should be used with
care.

There are still users who rely on DTD validation and in such
environments, the technique is not without its value.

| This is fine by me.
Thank you.
Be seeing you,
